Course Description
This course enables participants to understand the fundamental concepts of capillary
pressure from lab to saturation height model analysis.
The course will use a practical approach to discuss lab measurement options,
standard corrections, determining fluid contacts, and the free water level.
The course provides detailed knowledge of how capillarity affects hydrocarbon distribution
in reservoir rock,
And how the value of capillary forces can be used to deduce valuable information about
rock properties including pore
throat sizes, pore geometry, porosity, and permeability. Many exercises will be discussed to
illustrate the course
learning and provide students with experience using capillary pressure data for reservoir
characterization. Exercises
will be done on the computer using spreadsheet software. At the end of the course,
participants will be able to
complete a capillary pressure analysis and saturation Height model based on petrophysical
rock types.
